So I am getting my barrel threaded this week. Already cut the shroud off of the FSB but I am having some trouble figuring out how to tighten the slant brake on to the threads once it is done.

I have this M14-1LH slant brake from CNC Warrior.

I am using a M14 crush washer from them as well.

What do I use to crank down the slant brake on the crush washer without damaging the metal?

I just put a brake on my saiga at the end of last year. I was lucky enough to pick up one that came over with an AKM barrel that was factory threaded.

I used a crush washer as well, I found a website that manufactured a crush washer meant for 7.62 AKs (mainly just for saigas im sure). I had a horrible time trying to get it to "crush" so I could time the brake. It will probably be a little more difficult since your slant brake doesn't have flat sides to grip it with, perhaps a heavy duty strap wrench will work?

I can try a strap wrench but I dont think that will give it enough torque to get it tight. I guess it all depends on how far I have to turn it once it gets tight.

I also bought one of their AK74 style brakes:

I think this one would be fairly simple. I plan on just sticking a long screw driver masked with tape thru the big ports on the side to get some leverage to crank it down.

The slant brake is the one that has me scratching my head.

you will need to screw it on and tighten it, if it's not right, sand down your crush washer. Just trial and error to get it right, you might want to use some kind of protective cover on your brake when tightening it to avoid scratching it.

This is what I did when I couldn't get the crush washer to crush at all.

thats what i was thinking. what could i use to protect it that wouldn't slip when I torque on it? I think masking tape or duct tape would just slip right off.

Yep, that little bugger doesn't crush at all.

Have you considered replacing the front sight base with an original AKM one? It would be "correct" looking and you wouldn't have to mess with crush washers.

yes i have and I decided to keep the current FSB and just thread the barrel. I am not looking to make it 'correct' but rather just get the functionality of a brake without spending a lot of cash on this rifle.

What about staking the crush washer where the retainer notch is on the brake to prevent it from moving? Do you guys think that is necessary?

It's supposed to have a detent to keep it from moving. Just get an adjustable wrench and a towel and crank down on it. Don't know if it'll line up correctly but you get what you pay for.
